These days trains are mundane things. My encounter with them is when I sit at a crossing watchiing the Juice Train go by.I think little of the technology of them,, instead noticing how the graffiti artists are careful not to paint over logos or the identifying numbers of the cars. It must be an unwritten rule.

At one time trains were new and on the fore front of transportation. They were iconic. As these old railroad posters show, in their day the trains' modern lines, power and the exotic locations they could carry one to were emphasized.
